Review: Turns Rusty Metal Into Showroom Shine - This flap disc is the real deal. DEWALT slapped some zirconia grit on a wheel and basically handed you a surface-smoothing weapon of mass reduction. Whether you’re cleaning up welds, smoothing edges, or shaving down that "oops" cut you swore was straight—this thing handles it like a champ. Durability? Let’s just say it outlasted my attention span and my playlist. It cuts smooth, runs cool, and doesn’t shred itself to pieces halfway through a job like those bargain-bin brands. Put it on your grinder and let it work its magic. You’ll be turning rough steel into buttered toast in no time.
Review: Good price and High Quality - I used this along with an angle grinder to sharpen my lawn mower blades. It did a great job and I did not notice any damage to the disc after the job was done. I anticipate being able to reuse this disc for many more blade sharpenings. It was able to successfully sharpen the blade and I knew it was working from all the sparks that were generated at the time. I think this is a great value.

## Questions & Answers

**Q: is it 4-1/2 x 1/4 x 7/8?  I notice it is only described as 4-1/2 x 7/8.  Pls help.  Tks**
A: Yes. 41/2 diameter x 1/4" thick with a 7/8" hole ( bore)

**Q: Is there an adapter to use on a 5/8 inch grinder**
A: should use same arbor back flange and securing nut as an ordinary grinding wheel without threaded arbor, usually comes with grinder

**Q: I want to shave a door down about 3/8 inch.  Would this work for the job?**
A: mostly, this is used for grinding metals. To cut 3/8" wood, you need a saw not a grinder.
Thanks

**Q: OK for glazed tile?**
A: I think it you used it with a variable speed grinder at the slowest speed it would work for cleaning up the edges. For glass I just use a random orbital electric sander with 100 grit, since glaze is essentially glass, I would use caution on a rough grit.
